IMPROVEMENT IN APPARATUS FOR MAKING PAPER BAGS.`

Specification forming part of Letters Patent No. 146,372, dated January 13, 1874; .application filed october 2f, 1873.

To all whom it may concern:

Be it known that I, WILLIAM WEBsTER, of

the town of Middletown, county of Butler and State of Ohio, have invented a new and useful Improvement in Machines for Making Paper Bags; and I do hereby declare that the following is a full, clear, and eXact description thereof, which will enable others skilled in the art to make and use the same, reference being had tothe accompanying drawing forming part of this speciication, in which- Figure l represents the plain top view of my improved machine for making paper bags. Fig. 2 represents the pasterframe detached from the main machine, and containing the wire and tin pasters proper, and ready for use. Fig. 3 is a side elevation, showing the wheel E, cords e e, and treadles Nos. 1 2.

A denotes the forked gage, which is actuated by treadles 1 and 2. Cords e e connect the treadles with the grooved wheel E and the under side of the shaft of gage A in such a manner as to communicate the requisite reciprocating motion to the gage by meansof the Suitable guides upon the table serve to guide the gage-shaft in its action backward and forward. The pastenframe B has its longitudinal central piece hinged at fr, nea-r the rear edge of the table, and its front end is provided with handle d. This frame is constructed of slotted pieces secured adjustably together, and to the central hinged piece, by bolts and nuts, and carries the pasters, which are se cured to it. The paster Y, secured to the right-hand side of the frame B, is made of a strip of tin, occupying a vertical plane, so that its lower edge maybe dipped into a long pastepan upon the table, and there are two angular pasters secured to the left-hand side of the paster-frame; and there is a suitable paste` pan on the table to receive them also from time to time in the operations of pasting. The

' `object of the slotted pieces which are used in the construction of the paster-frame is to provide for such adjustments as will permit diiferent sizes of pasters or paste-carriers to be used, so as to make bags of diiierent sizes; and, for the like purpose, the prongs of the forked gage Amay be adjusted laterally, so as to gage the the bottoms of the different sizes of bags. `The under side of the shaft of the forked gage is grooved to give space for the cords e c, which also occupy grooves in the periphery of wheel E, and connect with their respective treadles l and 2. The former C upon the table is a sheet of tin. Different sizes of former may be used, upon which the bag is formed.

The operator stands in front of the table, several sheets of paper being placed on the table under the former O, ready for use; and, after the paste is applied, in the first instance, to the right-hand margin of the upper sheet of paper, it is folded, by hand, over the former to form the body of the bag, and then the operator turns up the uppermost half of the bottom of the bag, and presses it down upon the body of the bag, at the same time holding the central edge of the under portion of the bottom of the bag down upon the table; thus the edges at the corners of the former C are drawn inward, and fold down, so that they resemble two letters V arranged thus, ll At this stageof the work the operator, by means of the proper treadle, thrusts the reciprocating forked gage over the folded bottom, and, with his right hand, swings the paster-frame over thecenter of the table, and brings the an'gu lar paste-carriers. incontact with the edges of the folded bottomof the bag, and at the same time the straight pastef carrier `is brought in contact with the rightlhand margin of the `nent sheet of paper on the table; then the pastenframe is returned tothe paste-pans, and the upper and lower corners of the folded bottom of the bag are folded over the respective prongs of the forked gage, when the latter, by means of the proper treadle, is withdrawn. The final operation isto smooth down or compress the pasted bottom of the sack with a hand-pad, and withdraw the bag from the former C.

I have devised the stop YV, secured to the table top near its rear edge, which limits the lateral movements of the paster-frame. This stop is provided with two notches, o c, correspondin g with the width of the hinged central piece of the paster-frame. The right-hand notch determines the position for dropping the paste-carriers into their pans, and theleft hand' notch also guides the hinged central n'ATENT EEIcE.u

piece of the paster-'ranle, so as to cause the pasters to descend and deposit their paste at the proper places upon the paper; 'and the bottom of bag being made, the paster-frame B is pivoted as described, and swings upon the its pivot, when Operated by hand, as specied.

Having fully described my improvement in paper-bag machines, I claim- 1. The swinging frame B, having combined with it the adjustable and removable angular past-e carriers, and the adj ustablc straight paste-carrier, as described, for applying paste to the seams of paper bags.

2. In combination with paste carrying frame B, the stops W, as described.

3. The adjustable reciprocating gage A,hav ing laterallyadjustable guide-iin gers, for determining the lines for folding the bag bot toms, substantially as specied.
